2" 0 all whom it may concern.-

Be it known that I, MILO B. RUNYON, a citizen of the United States,residing at Fort Buford, in the county of Buford and Territory ofDakota, have invented a new and useful Picket-Pin, of which thefollowing is a specification.

The invention relates to picket pins or stakes for holding horses; andit consists in certain improvements in construction, hereinafter pointedout and claimed.

In the drawings, Figure 1 is a side elevation or plan of the improvedpicket-pin. Fig. 2 is a longitudinal section with the anchor collapsed.Fig. 3 is a similar section with anchor extended and plunger partlywithdrawn. Fig. 4 is a detail of the plunger; Fig. 5, a detail of oneflukeof the anchor.

A indicates a tubular stake or pin, which can be conveniently made of ametallic pipe having a closed and sharpened end. Near the sharpened endof the stake are holes or mortises B on opposite sides of the tube. Nearthe upper end of the pin there is a ring, G, which is attached to lugsor projections D on the pin. The rod E fits tolerably accurately intothe tubular interior of the pin A. Near the lower end of this rod thereis a mortise or slot, F, in which flukes G, which form the anchor, arepivoted. These fiukes are so attached as to fold into the slot F, whendesired. At the upper end of the rod Ethereis a ring, H, which isattached [021. band, I,.which forms 'a swivel. The top of rod E, abovethe swivel, is formed into ahead, K, to retain said swivel.

The rod E may be insertedin thetube A, as in Figs. 1 and 2, and the pinis then driven into the ground, the rod being guided so that the ends ofthe flukes come opposite the holes The ends of the flukes G will tend toproject through the holes B, and if the rod E is then lifted .or pulledon the flukes will be projected from the mortises B into the ground,(see Fig. 3,) being restrained from expanding too far by shoulders, oneof which 5 shoulders is shown at M, Fig. 5. The anchor can be againcollapsed by driving down the rod E into the pin A, and, when collapsed,the pin can be lifted out of the ground by power applied to ring 0,which ring also serves as a suspensory device, and may be used also forholding a picket-rope when it is not desired to use the anchoringdevice.

The shoulders Mof the flukes are of such thickness that they will notpass through the slot F of the tubular stake, so that these shoulderscome to a bearing against the inside of the tube. The pivotal point ofthe fiukes is so far removed from the shoulders that the tlukes cannotturn to a right angle with rod E inside the tubular pin.

I clainr- 1. The combination, with the pointed hol-. low rodconstituting the body of a picket-pin and having side mortises, of a rodfitting within 6 5 the interior of said body, having expanding flukespivoted thereto, said flukes constructed to pass through the mortises inthe pin in expanding, and a swivel attached to the upper end of saidinterior rod, whereby a pull on the swivel tends to expand theflukes,substantially as shown.

2. The combination, with a hollow pointed pin having side mortises, asdescribed, of a slotted rod within the hollow pin, said rod havingflukes pivoted within the slot in position to pass through holes in thepin-body, and shoulders on the flukes acting as stops to prevent toogreat expansion of the flnkes by hearing on the body of the pin, allsubstan- 8o tially as described.
